First test of an 3He neutron spin filter The nuclei of a helium-3 gas (3He) can be polarised. Thanks to the strong spin-dependancy of the neutron absorption a bottle filled up with that polarised gas

Spherical polarimetry with CRYOPAD These movies show the adventures of neutron polarization during the passage through CRYOPAD and the sample. CRYOPAD is the acronym for “CRYOgenic Polarization Analys

Simulated experiment From neutron source to detector in a high-field configuration Neutrons from the reactor are moderated in the graphite hot source so that the maximum flux is at a short wavelength.
